Troubleshooting

The “Buffer Underrun” error message is displayed.

●Try the following:

•Lower the writing speed setting.

•Create an image file of the CD on the computer's hard drive.

•Defragment the hard drive.

•Close other applications such as screensaver, task scheduler, and so on.

•Turn hard drive power management off.

•Deactivate Active Desktop (for Windows users).

•Disable network access.

•Deactivate resident software (Items in Windows task bar or Mac menu bar).

•Make sure that the CD writing software is appropriately configured (See the documentation for that software).

•Connect the CRW8824IX drive solely to the host computer.

nIf there is a slower device connected between the host computer and CRW8824IX drive, the data transfer between CRW8824IX drive and the host computer will go slow, which may cause failure in writing a CD.

nErrors can occur if you vibrate the CRW8824IX drive while it is writing to disc.

nWhen doing packet writing on a CD-RW disc, the actual data capacity becomes approximately 100MB less than stated on the cover of the disc. It is because packet writing requires an additional area on the disc.

Unstable operations.

●Do you have several kinds of CD writing software installed to the same system?

Such a situation may cause conflict, resulting in unstable operations.

●Has dust or dirt collected on the disc surface?

If so, clean the disc surface using an air spray or by wiping using a lint-free cloth. Remember to wipe the surface from the center of the disc to the edge. Be careful not to scratch it.

Other symptoms

Your CD writing software does not recognize the CRW8824IX drive.

●That software you are using may not support the drive. Consult the software manufacturer for compatibility with the CRW8824IX drive.
